IMPROVEMENT IN SAWING'MACHINESJ Specification forming part of LettersPatent No. 206,512, dated July 30, 1878; application filed December26,1877.

To all whom it may concern: I

Be it known that I, ELBERT F. TILOOX, of Hoopeston, in the county ofVermillion and State of Illinois, haveinvented certain new and usefulImprovements in SawingMachines and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification, and in which Figure 1 is a perspective view of myimproved sawing-maehine; and Fig. 2 is a detached View thereof, partlyin side view and partly in section.

Like parts in the two figures are designated by like letters. I

This invention appertains to certain improvements in sawing-machines;and it consists of a lever fulcrumed in a supportingframe, or betweenuprights, and connected to a knee or right-angled lever at its angle orknee, and connected to a sliding bar carrying the saw, or to thesaw-handle; and, secondly, of aguiding device for the saw or its slidingpar, substantially as hereinafter more fully set orth.

In the annexed drawing, A A refer to a horizontal frame or base, uponwhich are secured uprights or a frame, B B. O is a lever, fulcrumedbetween the upper ends of the uprights B B, and provided with a handle,I), for obtaining an increased leverage and for operating the saidlever. This lever is 0011- nected, by a bar, D, to a rightangled or kneelever, E, fulcrumed at its angle or knee upon a pivot secured betweentwo arms of the uprights or frame B B, or in any other convenientmanner.

The lower arm of the lever E is connected to a sliding bar, F, carryingthe saw G, or directly to the sawhandle.

The sliding bar D or saw-handle is guided in an eye or loop, H, restingupon a support, h, fastened to the foundation-frame A A. This eye orloop H is provided with arms or plates H H, reaching back and pivotedbetween the uprights B B, the object of which is to permit of the loopor eye H being raised or lowered to enable the saw to be adjusted to itswork or lifted therefrom.

I is a hand-lever, fulcrumed between the uprights B B, and hooked orotherwise connected to the rear connectingpiece z of the guide-arms H H,by which the Vertical adjustment of the said guide and its arms may byeffected.

K is a foot lever or bar, hooked or otherwise connected to the lowerside of the guidearm connecting-piece i, to apply downward pressure tothe sliding bar D or saw-handle, in order to sink the saw as it cutsinto the wood, and thus hold the saw to its work.

By moving the handle I) up and down, it will be observed that theright-ai'igled or knee lever E will be so affected as to impart abackward and forward movement to the sliding bar and saw, by which thelatter will be caused to cut the wood.

L is a fly or balance wheel, secured to an axis mounted in the arms ofthe uprights or frame B B, and linked, as at Z l, to the lever or beam0, to impart a certain amount of mo mentum to the machine.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is- I 1. In a sawing-machine, the combination of theknee-lever E, saw-bar F, handlever I, and arms H H, substantially as andfor the purpose set forth.

2. The combination of the beam 0 with intermediate mechanism foroperating the sawhandle I, link I, and balance-wheel L, substantially asand for the purpose set forth.

3. The hand-lever I, in combination with uprights B B, sliding bar orsaw-handle guide, and adjusting device consisting of the loop or eye Hand arms or plates H H, substantially as and for the purpose set forth.

4. The foot-lever K, in combination with the device consisting of theloop or eye H and arms or plates H H, substantially as and for thepurpose set forth.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in presonce of two witnesses.

ELBERT F. WILGOX.
